HERNIAL TRUSS.

SPECIFICATION forming part of Letters Patent No. 240,479, dated April19, 1881.

Application filed January 28, 1881. (Model.)

of Jordan, in the county of Onondaga, in the State of New York, haveinvented new and useful- Improvements in Hernial Trusses, of which thefollowing, taken in connection with the accompanying drawings, is afull, clear,

and exact description.

The nature of this invention consists in certain improved means foradjustably connecting the pad to the main supporting plate or arm of thetruss.

The invention is fully illustrated in the accompanying drawings, whereinFigure 1 is a back view of my improved truss Fig. 2, a longitudinalsection on line w 00 in Fig. 1; and Figs. 3 and 4 are side and rear faceviews, respectively, of the pad proper and the supplemental padconnected therewith.

Similar letters of reference indicate corresponding parts. 7

A denotes the plate or arm, designed to hold the pad P in its requisiteposition over the hernia. Said arm is adjustably connected to the usualwaistband by means of a plate or bar, a, which is provided at oppositeends with suitable means for the attachment of the band, and has alongitudinal slot, through which a screw, 1), passes, said screw alsopassing through a longitudinal slot, 0, in a bar, [1, on the arm A, andis provided on its end with a nut, 'n, which is countersunk in a groovein the back of the bar d, and engages ledges or ways 6 at the sides ofthe slot 0. The screw b serves both as a pivotal and a clamp screw, and,in conjunction with the slotted bars a and d, affords the necessaryadjustability of the position of said arm in relation to the band. Thearm A is clamped in its desired position by tightening the setscrew 1),and is further secured by means of a plate, f, which is pivoted in theslot 0 of the bar d, and has a segmental slot, 9, through which aclamp-screw, h, passes,said screw having a nut, 12, which rides on theways 0 at the back of the bar (1, before described. The plate f has itsedge adjacent to the plate a serrated or corrugated, to engage withcorresponding serrations or corrugations on the edge of the plate a. andthus effectually prevents slipping of the latter.

In order to make the plate a reversible end for end, and thus adapt itfor either side of the abdomen, I provide both edges of the said platewith the aforesaid serrations or corrugations.

The ledges or ways 0, on which the nuts 01 n ride, are inclined from theends of the slot 0 toward the center thereof, thereby producing upon thenuts, when tightened, a Wedging action, which crowds them toward eachother, and thus overcomes all danger of the plates a and f workingloose.

The bar 01 is placed lengthwise the arm A, and connected thereto bytrunnions'i on the extremities of the former passing throughjournal-bearings k on the latter, so that the arm is allowed to turn andaccommodate itself to the movement of the person wearing the truss. Thetrunnion on the lower end of the bar at has a projecting-prong, s, towhich is hinged a bar, I, which, in turn, is hinged on the pad 1? by apintle passing transversely through said bar I. The end of the prong shas on its under side a hook or notch, m, which engages the top of anut, 0, on a set-screw, p, insertedthrough the top of the bar Z, and inconjunction with another set-screw, q, applied to the lower or oppositeend of the bar I and bearing on the back of the pad, prevents the baseof the pad from yielding to outward pressure. By proper manipulation ofthe set-screws p and q the base of the pad can be set at any desiredangle to the plane of the arm A and adjusted to bear on the hernia withgreater or less pressure.

The top portion of the pad is yieldingly pressed inward or toward theabdomen by means'of a spring, 12, interposed between the upper-end ofthe bar I and upper part of the pad. This feature of holding the padagainst the hernia by a rigid or unyielding support on the base of thepad and a yielding support at the upper part thereof is one of the chiefpeculiarities of my invention, as by that means the hernia is moreeffectually retained than by a pad supported yieldingly at its base, ashas heretofore been customary.

R represents a supplemental pad applied to the base of the pad P, forthe purpose of arresting the viscera which may accidentally escape fromunderneath the pad P proper, said pad B being connected to the pad P bymeans of a spring-plate, r, secured to the back of the pad P by a screw,t, and having at the base of said pad a forward bent portion, at, onwhich the supplemental pad R is pivoted.

Having described my invention, what I claim is 1. In combination withthe supporting plate or arm A, the reversible plate a, serrated orcorrugated at its two longitudinal edges, and the plate f, having acorrespondingly serrated or corrugated edge, and the clamping-screwsband h, applied respectively to said plates, substantially as describedand shown.

2. In combination with theplates aandfand their clam ping-screws b andh, having nuts n n, the bar d, provided with the slot 0, and thecentrally-inclined ways e, substantially as described, for the purposeset forth.

3. In combination with the plate a and arm A, the bar 01, havingtrunnions i in bearings 70 on the arm A, substantially as shown and setforth.

4. A hernial truss provided with a firm or unyielding support for thebase of the pad and with a yielding support for the top of the pad,substantially as set forth.

5. The combination, with the arm A, of the bar d, provided with theprong 8, having hook m, and the pad P, hinged to said prong, and havinga set-screw, 12, provided with a catch for engaging the hook m andlimiting the swinging movement of the pad in one direction,substantially as described.

6. In combination with the arm A, the bar d, having a prong, 8, providedwith the hook m, the bar Z, pivoted to the pad and to the prong s, andprovided with the screw 1), nut o, and set-screw q, substantially asdescribed and shown.

7. In combination with the arm A, the bar 61, connected to said arm, andhaving a prong, 8, provided with hook 112, the pad P, bar I, pivoted tothe pad and to the prong s, the screw 19, having nut o, the set-screw q,and the spring 2;, all combined and operating substantially in themanner set forth. r

8. In combination with the pad P, the plate 4, having the bend a, theset-screw t, andthe pad R, pivoted on the bent portion u, allsubstantially as shown and described, for the purpose set forth. 1

In testimony whereof I have hereunto signed my name and affixed my seal,in the presence of two attesting witnesses, at Syracuse, in the countyofOnondaga, in the State of New York, this 15th day of January, 1881.
